 {{{
 With CVS HEAD (19 October 2005 Australian morning)
 the following minimal modifications to the HGL library
 give a runtime error in the "GTest.exe" example program:

 =======================================
 ...
 handleEvent: Before getMessage.
 handleEvent: Before yield.
 GTest.exe: internal error: resumeThread: thread not
 found
     Please report this as a bug to glasgow-haskell-
 bugs at haskell.org,
     or http://www.sourceforge.net/projects/ghc/
 =======================================

 Without those two putStrLn () calls, none of the three
 example programs "GTests.exe", "Tests.exe"
 or "HelloWorld.exe" displays a Window.

 With those two putStrLn () calls, all three example
 programs present their windows and both "Tests.exe"
 and "HelloWorld.exe" appear to run perfectly (although
 note that I have not seen them running at all other than
 in these tests).

 Cheers
